I already said: because it's fun to improve your skills and also to compete with other humans. Rubik's cube is just one possible way to do this. Chess is another. Counter Strike is another. Running fast is another. Etc. etc.

Also: competeting with other humans is also a form of socialization. And most humans like that.
